Skora was close to quitting football before a French specialist repaired the damage done by surgery he underwent while at Preston North End.
The 25-year-old went almost a year without wages and hopes to repeat the performances he showed during a loan spell at Killie in 2004.
Skora suffered his injury in October of that year after his return to Deepdale and he broke down again while on loan at Walsall a year later.
Killie boss Jim Jefferies brought the classy midfielder back to Ayrshire in January last year but the knee was still giving him trouble.
It was only a trip to a French specialist who treated the likes of Robert Pires and Zinedine Zidane that stopped Skora giving up.
He said: "My knee was in bits, I could hardly train two days in a row. I tried everything with the physio but it didn't work.
"I had to go back to France in the summer and see a specialist and he told me I had to start off from square one. I paid for everything - operation, rehab.
"It was very, very difficult for me and my family. My wife and kids were very supportive.
"At one point I wanted to throw the towel in because it was getting too much.
"I was very close to calling it a day. I was ready to try anything just to get some income again because I was living on savings for about 10 months.
"And my savings are not Elton John's so at some point I had to get some money from somewhere.
"It's difficult when you have always been playing football to get back to reality.
"As a footballer you are gifted, you do what you always wanted to, it's like a hobby more than a job even though you take it seriously.
"So getting back to an eight or 10-hour shift a day would be difficult.
"But in a way I'm glad that injury taught me not to get carried away with the way you are living because it could happen to any of us, a bad injury and that's it.
"I've always had consideration for everyone else but now I have more."
Skora now wants to repay Kilmarnock - who put him up in a hotel as he made his return in the reserves over the past few months.
"The club has been top class," he said. "There weren't many clubs who would have taken a gamble on me, out of shape and with two operations on my knee.
"I want to pay that faith back and hopefully with a good pre-season under my belt I can get back to my best.
"I wasn't sure if I could ever play football again, so I'm enjoying playing in the reserves, to me it's like playing in the Champions League."
Skora insists he has no problem with Preston or the surgeon who failed to sort out his knee.
"I was really angry with the surgeon but I just wanted to get it done again and get through the rehab," he said.
"You can't really feel let down by anyone because it's life, you have to get on with it. I've got no hard feelings towards Preston or whoever.
"I'm looking forward, not backward."
